SPRING REMOVING AND APPLYING TOOL.

Application filed M15712,

" biles.

An important object is the provision of a device of this character which will operate to relieve the tension'o'n the spring so that application or removal may be efiected in a simple manner, means being provided for holding the parts against movement after they ar adjusted onto the'spring and have been operated to compress the same.

An additional object is the provision of a device of this characterv which will be simple and inexpensive in manufacture, easy to operate, which will be a great time and labor saver and a general improvement in th art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the device initially applied'to a Hassler shock absorber spring,

Figure 2 is a similar view showing the. device as operated to compress the spring and locked,

Figure 3 is an elevation taken at right an les to Figure 2,

igure 4 is a detail perspective view of the neck and swivel head,

Figure 5 is a perspective view of the looking pawl and v igure 6 is a cross section on the line 6-6 of Figure 1.

Referring more particularly to the drawings the letter A designates a Hassler shock absorber spring and it will be noted. that this spring is not only spiral but also tapered or conical in its general contour. In carrying out the invention I provide an elongated lever 10 having one end constituting a handle'll and having its other end formed as a flattened and elongated nose 12 1922. Serial No. 574,577..

terminating in a lip 13. Secured to and extending laterally from the intermediate portion of this lever is an arm 14 which is of U-shape and which straddles the lever.

The securing might be efi'ected by means of rivets, spot welding or brazing. At a point spaced from the arm 14 the lever 10 is formed with a series of ratchet teeth 15.

Pivoted at 16 within the free end of the arm 14 is a lever 17 having one end constituting a handle 18 and having its other end notched as shown at 19 to define a neck 20 which is relatively small and which extends toward the nose 12. This neck terminates .in an extension 21 which is substantially parallel with the lever 17 and upon which is swiveled a head 22 having its corners cut away as shown at 23.

Pivoted at 24 upon the lever 17 is a pawl 25 which may be formed as a strip of metal bent at right angles intermediate its ends as shown at 26 and having its free end forked at 27 and straddlingly engaging the lever 10 in engagement with the teeth 15.

In the operation of the device the nose 12 is put through the second coil B of the spring which is the bottom or base of same. The head 22is then placed on top of the spring at the point where the shock absorber rests thereon, and the purpose of the swivel and neck 20 is, to allow clearance of the tool for compressing the spring. By putting the foot on the nose 12 and pulling upwardly upon the lever 17 a compressing action will result which will compress the spring A to the desired extent. The pawl 25 engaging the teeth 15 operates to lock the device in this position. The lip 13 on the nose 12 operates to prevent the device from slipping out of engagement with the spring. For securing the best results it is advisable to use a small block of wood tapering, say, from one inch to three inches and about six inches long, this block to be driven under the end of the car spring to take the weight off the shock absorber.

From the foregoing description and a study ofthe drawings it will be'a parent that I have thus provided a simp y constructed and consequently inexpensive device for the purpose specified which will operate more rapidly and whichwill be a great time and labor saver especially as I have found from actual experience that the spring may be removed in less than a minute as compared with the ordinary method which requires from thirty minutes to an hour.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim: a I 1. A tool of the character described comprising an elongated lever having one end terminating in a nose formed with a lip, a second lever pivotally connected with said first named lever and terminating in a neck, a head swiveled on said neck and disposable within the smallest convolution of a tapered spiral spring, said nose being insert-able between two of the larger convolutions, and a pawl and ratchet for locking said levers againstv movement.

2. A device of the character described comprising an elongated lever terminating at one end in a flattened nose having a terminal lip, an arm rigidly secured to and extending laterally from said lever intermediate the ends thereof, a second lever pivotally connected with the free end of said arm and having one end constituting a handle and its other end notched to define a' neck extending toward said nose,

said neck terminating in an extension subat one end in a flattened nose having a terminal lip, an arm rigidly secured to and extending laterally from said lever intermediate the ends thereof, afl second lever pivotally connected with the free end of said arm and having one end constituting a handle and its other end notched to'define a neck extending toward said nose, said neck terminating in an extension substantially parallel with the second named lever, a head swiveled upon said extension and having its corners cut away, said first named lex'er being formed with ratchet teeth, and a pawl pivoted upon the second named lever and having a forked end co-operating with said teeth.
